Network Troubleshooting Tool in Batch Scripting

Network Troubleshooting Tool in Batch Scripting | Automate Basic Network Diagnostics

Network issues are among the most common problems faced by IT Support Engineers and System Administrators. Instead of running multiple commands manually, you can create a simple Batch Script that gathers important network information in one place.

In this tutorial, we'll build a **Network Troubleshooting Tool** using Batch Scripting.

Batch Script

How the Script Works

# Step 1: Display a Heading

• echo ===== NETWORK INFORMATION =====

This makes the output easier to read and identifies the purpose of the script.



# Step 2: Display IP Configuration

• ipconfig

The ipconfig command shows:

• * IP Address
• * Subnet Mask
• * Default Gateway
• * Network Adapter Details

Example:

• IPv4 Address . . . . . . : 192.168.1.10
• Default Gateway . . . . : 192.168.1.1

# Step 3: Test Internet Connectivity

• ping google.com

The ping command checks whether your system can communicate with another device or website.

Successful result:

• Reply from 142.250.xx.xx

Failed result:

Request timed out.



# Step 4: Check DNS Resolution

• nslookup google.com

The nslookup command verifies whether DNS is resolving domain names correctly.

Example:

• Name: google.com
• Address: 142.250.xx.xx

This helps identify DNS-related issues.


# Step 5: Trace the Network Path

tracert google.com


The tracert command shows the path packets take to reach a destination.

This is useful when:

• * Websites are slow
• * Connections are dropping
• * Network routes need troubleshooting

# Step 6: Keep the Window Open

pause


This allows you to review the results before the Command Prompt window closes.

Sample Output

===== NETWORK INFORMATION =====

• Windows IP Configuration
• Reply from google.com
• DNS Lookup Successful
• Tracing route to google.com

Why Use a Network Troubleshooting Tool?

Instead of running commands individually, this script:

• * Saves time
• * Collects diagnostic information quickly
• * Simplifies troubleshooting
• * Helps identify common network issues

Real-World Uses

IT Support Engineers and System Engineers use similar scripts to:

• * Verify internet connectivity
• * Check DNS resolution
• * Troubleshoot user network complaints
• * Collect diagnostic information
• * Perform initial network health checks

This type of script is especially useful during Help Desk and Desktop Support operations.

Common Commands Used

Interview Questions

# What does ipconfig do?

• It displays network configuration details such as IP address, subnet mask, and default gateway.

# What is the purpose of ping?

• It checks whether a device or website is reachable over the network.

# Why is nslookup used?

• It verifies whether DNS is resolving domain names correctly.

# What does tracert do?

• It displays the path packets take to reach a destination.

# Why should network diagnostics be automated?

• Automation saves time and helps troubleshoot issues more efficiently.

Conclusion

A Network Troubleshooting Tool is a practical Batch Scripting project that combines several important networking commands into a single script. By using ipconfig, ping, nslookup, and tracert, you can quickly gather information needed to diagnose common network problems.

For aspiring IT Support Engineers, System Administrators, and future System Engineers, this is an excellent project to practice and add to your scripting portfolio.
